Problems solved by technology
[0006] In order to solve the above-mentioned deadlock problem that the air-energy water heater cannot be operated by using temperature difference power generation, and the existing air-energy water heater still has the problem of inconvenient wiring from the external unit to the water tank, the wiring length of the temperature sensor is difficult to follow. Application matching, the problem of unsightly installation, the problem that the wiring of the temperature sensor is too long leads to the problem of increasing the cost, and the problem of the hidden danger of wrong connection of the connecting line. The present invention provides an air energy water heater temperature difference power generation control system, a water heater and its Control Method

Embodiment 1
[0052] For example, when the unit is installed for the first time, the debugging tool 7 sends the ID of the water tank controller 6 to the unit controller 8 via Bluetooth, and the unit controller 8 records the ID;
[0053] At this time, the temperature in the water tank is low, enter the debugging mode, and the debugging tool 7 forces the unit controller 8 to operate the unit at the default temperature of 25°C. When the air energy water heater is heated, the R22 refrigerant connected to the refrigerant inlet pipe of the water tank can reach 95°C , R134A refrigerant can reach 75°C, and there is a temperature difference of tens of degrees from the ambient temperature, thus generating relatively stable electric energy;
[0054] The thermoelectric power generation control unit 63 checks the voltage of the electric energy stored in the power storage unit 5 every minute, and judges whether the voltage is greater than a preset threshold. When the control unit 63 determines that the p...

The invention relates to the technical field of water heaters, particularly to an air energy water heater temperature difference power generation control system, a water heater and a control method thereof; the control system comprises a water tank controller, a debugging tool and a unit controller. The water tank controller is used for collecting temperature information of the water tank and sending the temperature information to the unit controller; the debugging tool is used for sending debugging order to the unit controller; and the unit controller is used for receiving temperature information or receiving the debugging order of the debugging tool and controlling a unit to operate; compared to the prior technology, the debugging tool is used for operating the unit by force, an infiniteloop problem that the water tank controller with no electricity when leaves factor causes the water tank controller can't operate is solved; temperature difference power generation method is adoptedto power the water tank controller, and barge line is not need, installation is convenient and good looking, wrong connection of line is avoided, meanwhile cost of connecting lines is reduced.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to an air-energy water heater thermoelectric power generation control system, a water heater and a control method thereof. Background technique [0002] Thermoelectric power generation technology uses the temperature difference between high and low temperature heat sources, uses low boiling point working fluid as the circulating working fluid, and uses the high temperature heat source to heat and evaporate the steam generated by the circulating working fluid to drive the turbine on the basis of the Rankine cycle. Power generation technology. Its main components include evaporator, condenser, turbine and working fluid pump. The working fluid in the evaporator is heated by a high-temperature heat source and evaporated. The evaporated working fluid expands adiabatically in the turbine and pushes the blades of the turbine to achieve power generation. Purpose, the working fluid af...
